LITTLE B. JOHNSON, OF FRESNO, CALIFORNIA.

LIQUID-COOLER.

To all whom it may concern:

Be it known that I, LITTLE B. JOHNSON, a citizen of the United States, residing at Fresno, in the county of Fresno and State of California, have invented a new and useful Liquid-Cooler, of which the following is a specication.

The invention relates to improvements in liquid coolers.

The object of the present invention is to improve the construction of liquid coolers, and to provide a simple, eiiicient and comparatively inexpensive cooler, adapted for cooling water, milk, or other liquid, and designed especially for use in connection with a city or other water supply, and capable ofiutilizing the same for supplying the cooler with drinking water and also for spraying or sprinkling the cooler to reduce the temperature thereof through the evaporation of such moisture.

Wit-h these and other objects in view, the invent-ion consists in the construction and novel combination of parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claims hereto appended; it being understood that various changes in the form, proportion, size and minor details of construction, within the scope of the claims, may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

In the drawings :kFigure 1 is a central vertical longitudinal sectional view of a cooler, constructed in accordance wit-h this invention, and arranged for cooling water for drinking purposes. Fig. 2 is an end-elevation, the outlet of the tank being in section. Fig. 3 is a transverse sectional view on the line 3 3 of Fig. l. Fig. 4 is a detail perspective view of the tank. Fig. 5 is a detail sectional view, taken longitudinally of one side of the pan, illustrating the manner of securing the fabric covering to the same. Fig. 6 is a detail view of the drip pan. Fig. 7 is a longitudinal sectional view, the apparatus being arranged for cooling milk, or a liquid other than water.

Like numerals of reference designate corresponding parts in all the figures of the drawings.

In Figs. l to 6 inclusive in which is illustrated the preferred embodiment of the in- Specicaton of Letters Patent.

Application filed December 5, 1910.

Patented Aug. 29, 1911. serial No. 595,787.

vention, the apparatus, which is arranged for cooling water for drinking purposes, comprises in its construction a tank l, constructed o-f sheet metal, or other suitable material and preferably of substantially semi-conical shape, being tapered longitudinally and curved in cross section and having a flat bottom and a vertical rear wall, which is pierced by a water supply pipe 2. water supply pipe 2, which may be connected with the service pipe of the water supply of a city, or with any other suitable source of supply, is provided with a valve 3 fo-r controlling the flow of water to the tank l. The water supply pipe 2 is also connected by an upwardly extending vertical branch pipe 4 with a horizontal spray pipe 5, provided with a plurality of fine perforations 6, located within a trough 7 and adapted to supply water to the saine for moistening or saturating an absorbent fabric covering 8. The branch pipe 4 is connected with the water supply pipe beyond the valve 3, which does not aifect the flow of water to the trough, but only to the tank l. The lower end of the branch pipe 4 is rigidly connected with the water supply pipe 2 by a T-shaped coupling 9, and its upper end is connected with the spray pipe by a valve l0, and it serves to support the supply pipe and the trough in an elevated position above the tank. The valves may be of any preferred type and by their arrangement the iiow of water to the trough and to the tank may be independently controlled.

The trough, which is constructed of sheet metal, or other suitable material, is approximately semi-cylindrical, and the spray pipe pierces the end walls of the trough, which is open at the top. The perforations of the spray pipe are preferably located at the top, as shown, so as to discharge water upon the top portion of the covering, which extends across the trough. By arranging the spray pipe within the tank beneath the absorbent covering, there is no waste of water and the entire evaporation of the same contributes to the cooling of the tank. The tank may be supplied with water in any other preferred manner, and the water flowing over the sides of the trough will meisten or saturate the absorbent covering. Perforations, however, may be arranged at any other points, and

The

the absorbent covering, which is designed to be constructed of burlap or other suitable material, is substantially in the form of a tent and consists of a. horizontal top portion 11, inclined sides 12 and end flaps 13, which are equipped with fastening means 14, cons-isting of short cords or ties, but any other fastening means may be employed. rI`he sides of the covering are provided at theii lower edges with metallic binding strips 15, folded longitudinally to provide two sides oi' flanges and forming longitudinal beads or casings 16 at the lower edges of the inclined sides for the reception of rods 17, which pierce the front and rear walls of a drip pan 18, and secure the latter to the absorbent covering.

The drip pan is fitted against the bottom of the tank and it is supported in-position by t-he absorbent covering, and it is provided in its front and rear walls with perforations 19 for the rods 17, and it has pins or prongs 2O and 21 projecting from the central portions of its front and rearjvalls for engaging the end flaps of the covering to hold the same taut. The pins or prongs are located at the inner faces of the end walls, and the perforations 19 are spaced from the side walls, so that the lower edges of the absorbent covering are received wit-hin the drip pan. The front wall of the drip .pan is also provided at its central portion with a recess or outlet 22, receiving a faucet 23 of the tank, and also permitting water within the pan to flow from the front thereof. The faucet 23, which is arranged exteriorly of the absorbent covering, is connected by a short pipe 211 with the front end of t-he tank.

The water cooler may be used either out doors or in doors, and when used within a house it may be conveniently arranged over a sink, so that the water from t-lie drip pan may flow into the sink.

The tank is equipped at the top with an ice box or receptacle 26, provided with a removable cover 27 and having a drain cock or faucet 28, arranged adjacent to the plane of the bottom 29 of t-he box or receptacle and designed for use only when the tank is separated from the rest of the apparatus, and the saine may then be placed in a box of saw dust, or other material, which is a non-conductor of heat.

In Fig. 7 of the drawings is illustrated another form of the invention in which the spray pipe is connected with a water pipe 30, extending to any suitable source of supply. The tank in this fdrm of the invention is designed for cooling milk, or any liquid other than water, and the supply pipe 31 is designed to extend to a suitable pan or receptacle for supplying the tank with a liquid to be cooled. The milk or other liquid may be supplied to the tank in any other desired.

manner.
